Hey guys... My desktop started freezing up last night as soon as I reach my desktop on startup. The only thing I can do is open task manager. Through some guesswork, it seems like I have found the problem: Explorer.exe. If I shut down explorer.exe and restart it using run everything works fine. The problem started straight after running AVG 7.5 last night. It found 3 viruses, all of which were deleted (I ran all of my spyware/anti-virus, then deleting them - I was trying to find the cause of a smaller problem involving blank pages). Afterwards, I restarted to find that I couldn't click anything and my arrow always changes into a loading thingie when I move it over the taskbar. I have started noticing stuff crashing at random lately. If I'm browsing through folders my PC does occasionaly freeze up, the folders status changing to "Not Responding". I have also noticed other things, like explorer.exe having an error and not shutting down properly when I turn off my PC. Nothing as annoying as my current problem has ever happened before. Thanks in advance. P.S: I don't have access to the Windows XP disc.
